Take the tomatoes and cut the top off.
Use a small, sharp knife to cut out the middle of the tomato. Don't discard the middle because that will be used for the sauce.
Set the hollowed tomatoes aside to prepare for the stuffing mixture.
Add the meat, soaked mushroom, garlic, white onion, green onion, salt, pepper in a bowl. Mix well to make sure all the ingredients are combined.
To make sure the meat mixture is seasoned to your taste, fry up a small patty on the stove. If needed, you can adjust the salt amount here.
Spoon the seasoned meat mixture into the hollowed tomatoes. Continue until all the tomatoes are stuffed. Set the stuffed tomatoes aside and prepare the sauce.
